The NGRAN part covers the overall RAN architecture and explains the various ‘split-node’ options available. The RAN-internal interfaces (Xn, F1 and E1) and related signalling protocols are covered as well as the NG-interfaces towards the 5G core network. Radio interface layer 2 and layer 3 protocols are also included.

This course is kept up to date in step with the evolving standards for NR and NG-RAN. The contents listed in bullets below may therefore change slightly from one course event to the next. (Rel-15 is scheduled for completion Sept-2018 with some features moved to a ‘late drop’ March-2019. Rel-16 is expected to be completed March-2020.)


Reasonably good technical knowledge of the LTE physical layer and the LTE radio and RAN protocols is highly recommended but not compulsory.

NOTE: This course is not delivered with the FoldOut methodology.
